Description

Technical Field

[0001] The utility model relates to a large-scale fruit and vegetable peeling machine, which is applied to the field of fruit and vegetable peeling. Background Art

[0002] A fruit and vegetable peeling machine is a device for automatically removing the peels of fruits and vegetables and is widely used in the food processing industry. Existing peeling machines, such as the one with application number CN202010897138.1, are suitable for automatic peeling machines for multiple mangoes. The peeling machine places the mango on a base, fixes it through the guide wheel above, and then pushes the fruit delivery mechanism to the bottom of the top fruit shaft. The top fruit shafts at the upper and lower ends are controlled by a cylinder to fix the mango, and then the fruit delivery mechanism is removed to peel the mango. This method can fix the mango, but the device still has the following shortcomings: on the one hand, the base cannot be adjusted, which may cause the fruit to be placed unstable. On the other hand, if the fruit is placed unstable, deviations may occur during the fruit-topping process, causing the fruit to detach from the top fruit shaft, resulting in fruit loss. Therefore, in response to the above problems, the present utility model designs a large-scale fruit and vegetable peeling machine. Utility Model Content
